"This is almost unedited video showing KOTELNIKOV modulated by audio-rate oscillations.
The second module is a VCF in self-oscillation mode, sequenced by the same source as the SM042 module. (Elektron Analog Four is used as sequencer, which sends 1v/Oct pitch CV and unipolar envelopes for AM directly to this mini-system)
Since VCF CV input is also 1v/octave, a dramatic sound enhancement is possible using FM techniques as well as audio-rate Waveform Modulation and Hard-syncing."

"The SSSR Labs KOTELNIKOV is a digital voltage controlled wavetable oscillator module with morphing feature and built-in transient generator. This oscillator can generate number of sounds with diverse spectral content and combine them in various proportions. Kotelnikov can be used as a usual oscillator in a traditional subtractive synthesizer system, but it is also possible to use it as a complete voice module as it features shaped timbres, envelope generator and amplitude modulation.
Technical highlights
The sound engine sampling rate is locked to pitch and varies from 4.2 to 133 kHz, which gives very clear highs and uniform spectral content over the full range.
The Pitch resolution is 6 cents and CV input sampling rate is 6 kHz, which gives smooth analogish FM-ready CV response.
Analogue Amplitude Modulation input is bipolar, linear, rail-to-rail.
Kotelnikov contains 80 waveforms organized in 4 banks:
DRUID: Collection of Electric Druid VCDO wavetables (used with permission)
ATTACK: Interleaved dark/bright wavetables pairs
HARMONIC: Frequency-relative sinewaves
HD: Selected 12-bit wavetables
The firmware is written in Assembly language to ensure glitch-free operation and maximum working range.
The Transient Generator has 3 modes: AD/AR envelope generator or resettable LFO. Total time range of 0.4µs–10s is divided into 3 subranges. This generator is internally connected with FM and WM inputs, which helps you to achieve fluent, alive sound with no wires at all.
DIY Kit
This module can be purchased as Do-it-yourself kit that contains all necessary parts to build a complete module:
2x snow-white gold-plated PCBs. Made in Russia.
1x high-quality aluminium 14hp Eurorack front panel with protective film.
All electronic components, IC sockets, headers and hardware.
4x M3x6 screws and 30cm power cable.
The is almost completely through-hole kit except of SO8 reference voltage IC and voltage regulator IC. S that you don’t need to be an advanced DYIer to build your own Kotelnikov.
